Interesting if true, although if it is true I wonder how much longer that will be the case. A platoon of modern tanks is by no means cheap to operate, and it obviously puts a lot more soldiers in harm’s way to drive and maintain tanks near the front lines than it does to pilot a drone remotely from Las Vegas.
Edit to add: as for the “only effective if there’s little risk of getting shot down” part, isn’t that the whole point of drones? That you can put them into situations where there’s risk of getting shot down without losing any pilots? In the most recent battles that involved tanks it seems that air support played a crucial role for victory, so I don’t know if you’d want to operate tanks in any situation where you couldn’t also fly support aircraft, drones or otherwise.
